By:Wayne Parham Room modes, multisubs and flanking subs
…
When I first considered the multisub approach, it was prompted by papers written by Todd Welti. He did several tests that showed in-room amplitude response could be made smoother using multiple subs, and gave specific guidance about placement. His …

By:zheka Re: Why do you not use summed bass for flanking subs?
…found what maybe a potential compromise.
I still use summed signal.
I set crossover on the AVR fairly high - 160-200Hz. I then add 1st order low pass filter at a lower frequency (80-100Hz) directly in the DSP for my front subwoofer amplifier.
I …

By:j0nnyfive The most optimal placement for a single sub
…about what to do about bass. I like the multisub idea in theory, but it would be nice to have one mega sub and call it good. (mainly for decor and space reasons)
My question is, if you only had one sub, would your methodology for placement be any …

…you very much.
The box I am working on is also 10ft^3. The longest side is about 36" internal. It would not be used as true flanking sub but it may be low passed as high as 120Hz. If standing waves indeed form in this case, they would come form …
